[PATCH-next v2 00/20] CPU Utilization measurement and Perf refactoring

From: Ondrej Lichtner <olichtne(a)redhat.com&gt;

Hi all,

this is a second version of this patchset, v2 changes include:
* the Namespace.run method reuses other methods instead of duplicating
  code
* CPUStatMonitor comment explains the interval parameter
* CPUStatMonitor bugfix for signal handling
* fixed typo in IperfFlowMeasurement unit for cpu utilization
* move and reimplementation of the TRex measurement class to fit into
  the whole redesign of the lnst.RecipeCommon.Perf package
* updates to the OvSDPDKPVPRecipe:
    * stability improvements
    * refactoring to use the redesigned lnst.RecipeCommon.Perf package

Thanks,
-Ondrej

Hi all,

the core of this patchset is refactorization of the PerfTestAndEvaluate
recipe template into the lnst.RecipeCommon.Perf package implementing a
template for generic performance measurement tests, moving the
current MeasurementTools (Iperf and TRex) to fit this new model and
adding CPUUtilization measurements.

All of this is then incorporated into the BaseEnrtRecipe which is
currently the main user of the Perf recipe template.

There's also a couple of minor bug fixes and updates to the generic LNST
API based on the experience of using them wrt. the main changes of this
patchset.

!!!!!!!!
Some of these feel more like Proposals at this point though and I'm not
sure if they're good ideas. This is mostly related to the prepare_job
method of the Namespace class. It should definitely be considered and
thought about before fully accepting it.
!!!!!!!!

Additional note: this patchset breaks the ENRT/OvS_DPDK_PvP.py due to
the reorganization of the PerfRecipe. I wanted to send the patchset ASAP
so that it can get some reviews. I'll work on updating the OvS_DPDK_PvP
recipe while those reviews are coming in. And I won't merge this
patchset without the additional fixes for Ovs_DPDK_PvP...

Thanks,

-Ondrej
